Repairing Right Earbud Sound Issue on JBL Tune BT500 Wireless Headphones

The headphones worked properly for quite a while, then the sound in the right earbud started to cut out. At first, it was enough to arrange them properly and play, but now only one earphone is working. I had this with wired headphones, where I gave them to the service and there they made me an "armored" jack and for some time they were reveling. My question is, is it possible to do a similar repair somewhere or is it impossible in the case of wireless headphones?
Thanks in advance 😁

They can probably be repaired to work like the original. The symptoms say that some cables have probably been damaged and it is enough to resolder or replace them and the headphones will return to their original state. If you are not afraid, you can try to repair them or give them to someone who has done such things, usually the biggest challenge is to unscrew the headphones and then it's downhill.

Thanks, as it was the fault of the plug before, I was afraid this time that everything was lost 😆. I've never soldered, I don't have any tools for it, so I'll just give it to someone who knows about it. I found out what I wanted, so the topic is probably closed.
Thanks so much for your help
